White Oyster Mushroom Grain Spawn - 2 kg
Grain spawn is a little known secret weapon of the world of mushroom cultivation. It’s made from sterilised grains that have been inoculated with a live mycelium culture.
Grain spawn contains a lot of energy for the mycelium to consume. It’s a bit like rocket fuel for mushrooms. It’ll take off like wildfire once added to your bulk substrate.
Mother Nature works her magic using spores but in a controlled environment you need to tip the scales in your favour by using clean high-quality grain spawn so you are doing your best to ensure success.

Pleurotus Ostreatus is known as the white, pearl, beige, or grey oyster mushroom amongst a multitude of other names. Depending on where you are and who you’re talking to the white oyster species being referred to may be different due to the varying range of qualities.
Some ‘white oyster’ mushrooms are suitable for growing during the summer months, others are more suited to growing in winter. These impressive giants develop thick meaty caps when grown on hardwood and given plentiful fresh air.
White oyster mushrooms pack a big umami punch with every mouthful. More subtle in flavour than pink oyster mushrooms but with a thicker and meatier texture. Ideal for soups, stir-fries and deep-frying.
White oyster mushrooms will grow on a wide range of materials including sugar cane mulch, straw, hardwood, paper and coffee grounds.
For beginners we recommend starting with straw or chopped sugar cane mulch. Supplementation can be added in the form of coffee grounds or bran but will increase the chances of contamination.
White oyster mushrooms are considered to be a side-fruiting mushroom compared to the king oyster or button mushroom which are top-fruiting mushrooms.
Growing oyster mushrooms in buckets is a great project for first timers and more experienced cultivators alike. You can grow your own mushrooms at home using sugar cane mulch, straw or the cellulose rich material of your choice in conjunction with either cold or hot water pasteurisation.
Simple and easy to do using a few household items.
Humidity can be managed through a diligent misting and fanning regime, however the introduction of a humidifier and humidity controller can help automate the process and ensure consistency.
Adding a 6L humidifier and controller to a greenhouse with the addition of a USB fan is a quick and easy way to make a low cost fruiting chamber that delivers excellent results.
Mushrooms require humidity to grow. We recommend using a mini-greenhouse. Spraying the inside walls of the greenhouse will help raise humidity. A cheap humidifier can used to automate the process.
It’s important to ensure that the grow kit has fresh air exchange. Mushrooms produce carbon dioxide and will grow long and leggy if they require more oxygen.
Check the product pages for species specific requirements.
Alternatively you can build a Shotgun Fruiting Chamber (SGFC) from a few common items found easily in your local hardware store.
White oyster mushroom mycelium will colonise both grain spawn and bulk substrates very quickly. Full colonisation can often be expected within 7 – 10 days.
Store the substrate or grow kit in a humid location and wait for pins to form. Ideally humidity should be kept above 80% however fluctuations in humidity are well tolerated.
Summer varieties: 16 – 30 degrees Celsius (60 – 86F)
Winter varieties: 13 – 20 degrees Celsius (55 – 70 F)
These values are to be used as a guide only due to the differences between white oyster varieties available.
White oyster mushrooms like most oyster mushrooms are very demanding of fresh air and will grow long and leggy when requiring increased fresh air exchange.
